1.6.5. Pressure check in tyres

Pressure in tyres is convenient for checking a manometre and the compressor (it can be connected in a nest прикуривателя). Values of pressure are specified in the maintenance instruction. If pressure check in нагретых tyres it can be above on 20-30 кПа. In this case do not pit air to reduce pressure.

After certain run in kilometres it is necessary to check up depth of a protector of tyres. Small calibres are intended for this purpose 11 (fig. 5 see) which are established on the tyre according to fig. 10. Depth of a protector should make not less than 1,6 mm.

The tool and the adaptations used at maintenance service and repair: 1 — a hydraulic jack; 2 — a butterdish; 3 — support; 4 — a portable lamp; 5 — a sampler; 6 — динамометрический a wrench; 7 — ножовка; 8 — a wire brush; 9 — lamellar measuring щупы; 10, 11 — measuring instruments of size of deterioration of tyres
